A Correlation Between the Heat Affected Zone Microstructure and the Thermal History During Welding of HY-130 Steel.

Abstract

A study of microstructure as a function of distance from the fusion line was conducted for an instrumented weld in HY-130 steel plate. Thermocouples were positioned in the plate at various distances from the fusion line and were used to obtain the welding thermal history at these locations. A correlation was then developed between the microstructures observed and the thermal history experienced. Additionally, the tempering of the heat affected zones of the initial weld passes by subsequent weld passes was calculated and correlated with hardness and microstructural data. Finally, a further study of the metallurgical notch phenomenon postulated by Brucker was undertaken. (Author)
